The UN met on Saturday in Poland to discuss a draft agreement on climate change, which sources said was likely to pass, as exhausted delegates made compromises on some key issues but left other contentious problems to be resolved next year.

The result will not be the breakthrough campaigners and some countries were hoping for, but will keep discussions alive on formulating key aspects of the implementation rules for the 2015 Paris accord.

Five months after twin tragedies cast a spotlight on the state’s ailing orcas, Washington plans to spend more than $1bn to stave off extinction.

If enacted, a proposal from the governor, Jay Inslee, would knock down two dams, repair habitat and place a three-year ban on orca watching. Crucially, Inslee hopes to shore up salmon runs that feed the orca while cleaning and quieting the waters in which they live.

Slow progress on 2015 Paris agreement comes as scientists warn of need to get on track

Negotiators at the climate conference in Poland have inched closer to an outcome, as the official deadline for finishing a deal ran out.

The conference was meant to approve a rulebook which would govern how nations put into action the goals set in the landmark Paris agreement of 2015, when the world resolved to hold global warming to no more than 2C above pre-industrial levels, with an aspiration to limit temperature rises to no more than 1.5C.

At the COP24 conference, leaders lack the urgency felt by communities on the frontlines of a global threat

As wildfires burn, as temperatures rise, as the last remaining old-growth forests in Poland are logged, world leaders are in Katowice to negotiate the implementation of the Paris climate agreement. To outsiders, UN climate talks may seem like a positive step. Unfortunately, this is COP24.

For 24 years, world leaders have annually talked at each other instead of to one another in hopes of reaching an agreement on how to mitigate the climate crisis. In all that time, they have barely scratched the surface of an issue that the world’s top climate scientists say we now have 12 years to stop – and that is an optimistic estimate.

Supermarkets have increased their efforts to reduce the national food waste mountain at Christmas by offering shoppers edible produce nearing the end of its shelf life, as well as “wonky” sprouts, carrots and parsnips.

The wonky or “ugly” lines were being offered at cheaper prices in an effort to stop the rejection or waste of fruit and veg that was misshapen, had growth cracks or was much smaller or larger than average.

Coal, known as ‘black gold’ in Poland, has helped the country achieve energy independence. However, the high-polluting fuel has been linked to serious diseases and premature death. With COP24 climate talks under way in Katowice, pressure grows on Poland to reduce its reliance on the fossil fuel. But with 100,000 coal-dependent jobs in the country, switching to alternative sources of energy carries great economic risk. Here, Violeta Santos Moura explores the problem in her essay Dark Clouds

Displays of coal jewellery and coal soap, coal in a glass walkway beneath your feet, coal in the air that you breathe … the Polish hosts of this week’s UN climate talks have been anything but subtle in reminding delegates that we still live in a fossil-fuelled world despite the urgent necessity to move to a cleaner path.

The conference centre is near the mineshaft of the colliery museum in Katowice, the heartland of Silesia’s vast coal industry. The sponsors include JSW, the EU’s largest coking coal producer, and PGE, which runs the world’s second-largest fossil-fuel power plant.

Comments by science review board chairman add weight to fears that Trump administration is aiming to discredit research to justify scrapping regulations

A conservative science adviser to the Trump administration is casting doubt on longstanding research linking fossil fuel pollution to early deaths and health problems, worrying environmental experts.

At a meeting to review air pollution science compiled by staffers at the Environmental Protection Agency this week the advisory board chairman, Tony Cox – a consultant and statistician who has worked for the industry and criticized EPA standards – questioned whether soot from coal plants and cars can be directly blamed for asthma and cardiopulmonary problems.
